A Vietnam War veteran who confessed five years ago to killing a 4-year-old girl in a 1968 hit-and-run was trying to protect children when a woman drove her car onto a baseball field in Maine during a game, striking and killing him.

Screaming bystanders and ballplayers fled as Carol Sharrow, of Sanford, Maine, drove through an open gate onto the field Friday night, police said. Video shows the car driving around the infield, turning over home plate and then heading toward the stands behind third base.

Douglas Parkhurst, of West Newfield, was near the park's main gate before he was hit and Sharrow sped away, police said. Parkhurst died on the way to the hospital and no one else was hurt.

"It was awful," said Sanford resident, Karyn Bean, who said she saw Parkhurst being struck. "A car driving through the gate hitting a man who was pushing kids out of the way, then her driving up the road easily doing 50 to 60 miles per hour past us.

"It felt awful because we couldn't do anything."

Sharrow was scheduled to appear in court later Monday to face a manslaughter charge. She was to have an attorney appointed to represent her then.

Sharrow has two previous drunken driving convictions in Maine and New Hampshire, according to Sanford police Det. Sgt. Matthew Jones. Authorities have declined to say whether alcohol was involved on Friday.

Parkhurst was never charged in the hit-and-run death that killed Carolee Ashby on Halloween night in 1968. The statute of limitations had long run out when Parkhurst walked into a police station in 2013 and confessed after two interviews with investigators.

In his four-page confession obtained by the Syracuse Post-Standard during its reporting about the case, Parkhurst said he and his brother had been drinking before he hit the girl. He said his brother was passed out in the back seat.
